Several safety measures protect service technicians and homeowners from eye or skin UV exposure, including a lamp shutoff switch, and a sight glass for safe and easy lamp inspection. A protective cover with a safety interlock switch immediately deactivates the lamp before the service technician or homeowner can access or service the unit. The effectiveness of germicidal UV-C is limited once molds, which are more resistant to UV energy than airborne bacteria, have already formed on surfaces. See similar questions...

Yes, the fabric provides a complete block from UV rays. Our optional items, our Solar Shield and "Weather Wrap?", will provide the same protection for the screen runs. See similar questions...

Yes, MacroBins have a UV package added to the resin which very effectively protects bins from UV exposure. See similar questions...

Clothing must have a UPF (Ultraviolet Protection Factor) of at least 15 to be considered sun protective. A typical t-shirt has a UPF of 7 (Source: Morehouse School of Medicine). Splashskins are UPF 30 or above (blocking out 96-98% of the sun's damaging rays). Learn More! See similar questions...

Ultraviolet (UV) rays are located just past the violet portion of the visible light spectrum; sunlight is the main source. UV light is broken into three different types: UVA, UVB and UVC. UVA has longer wavelengths and passes through glass easily; experts disagree about whether or not UVA damages the eyes. UVB rays are the most dangerous, making sunglasses and sunscreen a must; they don't go through glass. UVC rays do not reach the Earth because its atmosphere blocks them. See similar questions...

Most people think that they're only at risk when they're outside on a sunny day, but UV light can go right through clouds, so it doesn't matter if the sky is overcast. The sun's rays are strongest between 10 am and 2 pm. Glare and reflections can give you trouble, so have your sunglasses ready if you'll be around snow, water or sand, or if you'll be driving (windshields are a big glare source).

No, our equipment is state of the art-digital x-rays. Which reduces patient exposure by 90%. The office follows American Dental Association guidelines as to the frequency of radiographs. See similar questions...

CAP UV-C and UV Plus products are equipped with high quality, high-output U.S.-made lamps for optimum performance and reliability. The hard quartz lamps are rated for at least 9,000 hours (1 year) when installed and used in accordance with the operating manual. Lamps may last much longer in some situations, but annual lamp replacement is recommended since the UV output of any lamp typically starts to drop off after about 9,000 hours. On/off lamp cycling will reduce lamp life. See similar questions...

The UV rays emitted by indoor tanning lamps do not emit sufficient energy to penetrate past the skin layers. Thus, despite claims and rumors to the contrary, internal organs are not directly impacted by longer wave UV light. See similar questions...

Caviseal will burn over and change color as well as lose a 1/16 of an inch in the first month. After it burns over the degradation action slows and you will lose about an 1/8" in four months. However we want it to burn over some because it creates a hardened shell on the face increasing its permeability and moisture penetration characteristics. Back to Top See similar questions...

NO, special maintenance is not required. Keep sharp objects out of the pool and from underneath the pool. See similar questions...

Yes. We have had our fabric tested in a university lab. The fabric blend is certified to an Ultraviolet Protection Factor (UPF) of 50+, the maximum rating given. This means that FOXGLOVES offer excellent sun protection. See similar questions...

No. The risks are approximately equal. For some time it was hoped that UV lamps could be made safer by making more use of long-wavelength (UV-A) radiation. That type of radiation is much less carcinogenic than the shorter-wavelength UV-B radiation, but one needs more UV-A than UV-B for acquiring a tan. See similar questions...

It's very common for customers to think our UV lamps are not efficient like competitors because they are low priced, but the fact is they are more powerful than most UV-C germicidal lamp products used in other UV air purifier systems. Plain and simple, we don't mark them up. You can find our same style lamp used in our UV air purifier at a competitor site for $45 each, and we even found another for $107 each, that's just ridiculous. The $22. See similar questions...

Either by direct destruction or the alteration of the organism's DNA or RNA. Either way ensures a halt to the pathogen's* ability to reproduce and infect. See similar questions...

The harmfulness of UV-B stems from the high energy of these light rays, which allows them to penetrate deeply into water, leaves, and skin. Because of this, increased UV-B radiation can harm the metabolism of cells and even damage genetic material. Although living organisms have always been exposed to some UV-B, cellular repair mechanisms evolved to protect against its damaging effects. The problem with increased UV-B is that it causes more damage than the natural protection can cope with. See similar questions...
